OIL-BURNER.

Specification of Letters Patent.

Patented Apr. 25, 1916.

Application filed February 10, 1916. Serial No. 77,448.

To all whom it may concern:

Be it known that I, J AMES G. ANDERSON, a citizen of the United States, and resident of San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Oil- Burners, of which the following is a spoolfication.

My invention relates to oil burners, and the object of my invention is to produce an improvement in oil burners for that type of burners generally known as distillate or liquid fuel burners.

In those burners now in use the fuel is usually fed through a pipe passing along one side of a cylinder in which combustlon takes place, across the rear end of said cylinder and back to the front on the opposite side of said cylinder, and thence to the point of discharge into an opening in the forward end of the cylinder. It is pointed out that in this form of generator it is necessary to burn considerable oil in the tray under the same before the generating pipes can be sufliciently heated to vaporize the oil contained therein.

The time consumed in burning the amount of oil required to heat the pipes and vaporize the oil therein makes the arrangement objectionable for practical purposes, and 1t is, therefore, the object of my invention to provide a means for more quickly yaporizing the oil and thereby rendering the burner more practical and efficlent, and consequently create a wider demand for its use.

With these and other objects in view, my invention consists in the novel' and useful provisions, formation, construction and relative arrangement of parts, members and features hereinafter described, and illustrated in the accompanying drawing, in which,

Figure 1 is a side elevatlon of my improved oil burner. Fig. 2 is a sectlonal view on line AA of Fig. 1. Fig. 3 1s a diagrammatical plan view of the oil vaporizing pipes.

Referring now more particularly to the drawing, 1 indicates a pan in which the device is positioned.

2 refers to a cylinder provided with supports 3 and with slots 4 out in the sides thereof. A cylinder 5 having a nut in one end is positioned concentrically in the forward end of cylinder 2 by screwing into the forward support 3 as shown. The pipes in which the oil is vaporized are shown at 789 and 10 respectively, joined in any suitable manner as by double elbows indicated at 11-12 and 13 respectively, to form a substantially W shaped conduit as shown in Fig. 3. Pipe 7 is the first member of this construction and is provided'with any suit able controlling valve as indicated at 14:, and 1s supplied with oil from any suitable source of supply not shown, and passes along one side of cylinder 2 to the rear thereof. Pipes 8 and 9 are not placed in the same plane with pipes 7 and 10 but are dropped beneath cylinder 2 as best shown in Fig. 2, the same passing forward a distance and joined by double elbow 12. Pipe 10 passes along the opposite side of cylinder 2 from pipe 7, to the forward end thereof where it is connected to any suitable form of needle valve as indicated at 15, the same being axially positioned with relation to cylinders 2 and 5.

When the burner is assembled as hereinbefore set forth, and connected to a proper oil supply, oil is admitted to pipe 7 through valve 14:, from whence it passes through members 1l-8--12-9 and 13 and 10 to 'valve 15. A small quantity of oil is now permitted to flow into pan 1 and is ignited. The resulting heat plays directly upon members 8-12 and 9 and to a lesser degree upon members 7-1113 and 10 and reduces the oil therein to a gaseous state whereupon valve 15 is adjusted as required and the burner is in full operation.

It may now be seen that the formation of the middle members 812 and 9 and their position close to pan 1 beneath the cylinder 2 greatly increases the efficiency of the burner by securing immediate, almost instantaneous results from the burning oil in pan 1, and consequently the burner may be started much more quickly and with less preliminary manipulation than with any of the burners of this general type now in use.

It is understood, of course, that changes in the minor details of construction may be resorted to within the scope of the'appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,-

1. A liquid fuel burner comprising a hollow cylinder closed at one end and having discharge slots formed in its side walls, a substantially W shaped generating tube havproximity to their respective sides of said cylinder and its middle members positioned in close proximity to the under side of said cylinder, a means of supplying fuel to one end of said tube, and, means connected to the other end of said tube for injecting the generated vapor into the, interior of said cylinder.

2. A liquid fuel burner comprising a hollow oylinderclosed at one end and havingdischarge slotsin its side walls and a secondfhollow cylinder concentrically positioned: in its other. end, a dischargenozzle so positioned as to inject generated vapor into the interior of said hollow cylinders, and a generating tube connected to a source of supply and passing rearwardly along one side of said first mentioned cylinder, thence downwardly and forwardly a distancecopies otthjs nfite nt luapg beohtainediforlfive cents each, by addressinglthe, Qommlfi loml'z rl'ltntm Washington, D.
